Can a brown eyed and blue eyed couple have a blue eyed child?

Someone with brown eyes may be carrying one blue allele and one brown allele, so a brown-eyed mother and a blue-eyed father could give birth to a blue-eyed child.

Can a brown eyed woman and a blue eyed man have a brown eyed child?

You need a working HERC2 and a working OCA2 to have brown eyes. Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child.

What are the chances of a mother who has blue eyes and a father who is heterozygous for brown eyes to have blue eyed children?

If both of you have brown eyes, then there is generally a 25\% chance that the baby will have blue eyes if both of you carry the recessive blue-eye gene. But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1\% chance of the baby having blue eyes.

How do I get green eyes?

Green eyes are a genetic mutation that produces low levels of melanin, but more than blue eyes. As in blue eyes, there is no green pigment. Instead, because of the lack of melanin in the iris, more light scatters out, which make the eyes appear green.

Can two blue eyed parents have a child with brown eyes?

Turning on a broken pigment making gene still gives you no pigment. You need a working HERC2 and a working OCA2 to have brown eyes. Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child.

Why do some people have brown eyes and some have blue eyes?

The brown gene dominates over the green one resulting in brown eyes. The reason these two genes can explain darker eyed kids with lighter eyed parents is that the two genes need each other to work. And that the blue versions are broken genes.

What is the genotype of a mother with blue eyes?

The most likely genotype for the mother is either Bb (heterozygous with both a dominant and a recessive gene) or BB (homozygous dominant) for the trait. If a seventh child had blue eyes, the mother’s genotype would be Bb, and the father’s genotype still would be bb. Suppose an XcXc female marries an XcY man.

What are the chances of having a blue and brown offspring?

The results are a 9 in 16 chance for brown and a 7 in 16 chance for blue. This assumes that any of four combinations of the two genes is possible. This is true for genes that are far apart or on different chromosomes. This does not tend to be true if genes are really close together like OCA2 and HERC2.
